Answer:
12.5%
Step-by-step explanation:
Given that he buys lemons at 6 for 10.
Then the cost price of 1 lemon = 10/6 = 1.6
Given that he sells at 8 for 15.
Then the selling price of 1 lemon = 15/8 = 1.8
We know that Gain = Selling price - cost price
= 1.8 - 1.6
= 0.2.
We know that Gain% = Gain * 100/CP
= (0.2 * 100)/ 1.6
= 12.5%.
Therefore the gain % = 12.5.
